This mop head cleans and protects your investment using just water. There's no need to add chemical cleaners or worry about crawling kiddos and curious pets. The thick pad goes to work with masses of precision-engineered microfibers, activated by water's cleaning power. Quick-grip hook-and-loop fasteners make it easy to attach and remove the mop head. To refresh, just toss in the laundry. Because, unlike single-use, throw-away refills, the reusable mop head is made to last and guaranteed to perform for 300 washes or 3 years. So much simpler, swifter, and savvier, it's hard not to share the news.
